Implementations of the invention are illustrated below by way of specific examples, and those skilled in the art can easily understand other advantages and effects of the invention from the content disclosed in this description. The invention can also be implemented or applied through other different specific embodiments, and various details in this description can also be modified or changed based on different viewpoints and applications without departing from the spirit of the invention. It should be noted that the embodiments are not limited to those described below.

A cosmetic mask of the present invention is a cosmetic mask that is worn on the face of a user, the cosmetic mask is configured to as to cover at least the cheeks. A nosepiece that conforms to the convex shape of the nose is preferably provided for convenience of positioning, and besides this nose piece it is also possible to provide openings for the mouth, eyes, and ears. For example, the cosmetic mask is preferably made of an elastic material such as silicone or natural rubber. In particular, silicone has tightening strength, and it is most suitable for being used in contact with the skin because it is often utilized for medical purposes.

A cosmetic mask, characterized by being provided with either or both of a pair of zygomatic muscle stimulators for applying electrical or ultrasound stimulation to locations corresponding to the zygomatic muscles of the user, and a pair of masseter muscle stimulators for applying electrical or ultrasonic stimulation to sides corresponding to masseter muscles, while being adjusted at appropriate positions on the face using the nosepiece, and the openings corresponding to the mouth, eyes, and ears, is provided.

A pair of stimulators for applying stimulation to the zygomatic muscles and masseter muscles, and stimulator fitting sections for fitting the stimulators to positions of the cheeks are provided on the cosmetic mask, and the cosmetic mask is configured so that at least some of the stimulators can be detached from the cosmetic mask.

With the practical examples below, although stimulators that are provided with electrodes that apply electrical stimulation to both zygomatic muscles and masseter muscles are shown, the embodiment is not thus limited. Although an example where some of the stimulators are detachable is shown, the stimulators do not need to be of a detachable type.

Also, although description has been given for a zygomatic muscle stimulator and masseter muscle stimulator that are configured to apply electrical stimulation, it is also possible to apply ultrasound stimulation as a well-known beauty treatment, and the stimulators of the present invention may be configured to use ultrasound. The cosmetic mask may also be configured to perform both electrical stimulation and ultrasound stimulation treatment.

FIG. 1 and FIG. 2 depict the front view and the rear view of a mask body (1) of the present invention are respectively shown in FIG. 1 and FIG. 2 . The mask body (1) is an elastic body that is integrally formed of silicone, and forms a mask section (10) that covers a lower half of the user's face from the user's eyes to the jaw, a horizontal band (11) which is a lateral fitting part that is provided extending in a lateral of the mask section (10), and a vertical band (12) with is a vertical fitting part that is connected to a lower end of the mask section (10) and is provided extending in the left and right directions when it is opened.

An upper edge section (13) that is formed in a concave shave so as to avoid contact with the eyes, a nosepiece (14) that is formed protruding three-dimensionally in conformity with the shape of the nose, and a mouth opening (15) that is opened to expose the mouth, are formed in the mask section (10).

The mask body (1) can be worn naturally by the user adjusting the nosepiece (14) and the mouth opening (15).

The nosepiece (14) may be configured to have a cutting that allows the nostrils to be exposed when wearing the mask, and through which the user's nose tip will protrude.

A stimulator fitting section (16) for fitting of the current generator is opened at a cheek position in the mask body (1). The stimulator fitting section (16) is not necessarily limited to being opened, as in this practical example, and engagement sections may be provided that engage with a skin side of the mask body (1), a plurality of openings may be provided to expose only the electrodes, grooves may be formed, or any other form may be used.

When adjusting the mask body (1) on the face, the mask section (10) is stretched in the lateral direction by passing the horizontal band (11) around both sides of the head and fastening hook-and-loop fasteners (11 a) and (lib) at the back. In this way a tightening effect is achieved by applying moderate pressure on the face, particularly on the cheek parts.

Further, the vertical band (12) is fitted by curving from the mask section (10) at a right angle to a lower surface of the lower jaw, and passing around both sides of the head, while applying tensile force towards the top of the head. The vertical band (12) is similarly attached with hook-and-loop fasteners (12 a) and (12 b).

By stretching the vertical band (12), both of the vertical band (12) and the mask section (10) below the vertical band (12) lift the cheeks upward to achieve a lift-up effect.

Besides the hook-and-loop fasteners, it is also possible to use hooks and one-touch buckles, magnets, etc., to attach the horizontal band (11) and the vertical band (12).

With the present invention, the horizontal band (11) and the vertical band (12) do not necessarily need to be provided, and as another method of constructing the mask section (10), for example, the mask can be fitted to the face with a separate band. Also, as an example of a horizontal fitting part, ear openings may be made, as disclosed in FIG. 8 , so that the mask can be hooked over the ears. It is also possible to not provide the vertical band, and only provide the horizontal band (11).

FIG. 3 , FIG. 4 and FIG. 5 depict the front view, rear view, and left side view of a current generator (2) according to the present invention. The current generator (2) is a generally triangular shape comprising a power supply button (20) on a surface that constitutes an outer surface of the time of fitting, and adjustment buttons (21) and (22), and has a notch (23) formed in a part thereof.

Three mask side electrodes (240), (241), and (242) are provided on a rear surface.

The shape of the current generator (2) is not limited to being generally triangular, and may also be formed in any shape, such as a circle, an ellipse, a rectangle, or a hexagon etc. In particular, it is preferable to make the current generator a shape that is not symmetrical so that the fitting direction is clear.

With this practical example, as described above, a structure that applies electrical stimulation is shown as a stimulator, with a control section, not shown, that controls electrical current being provided inside the current generator (2), and a feed section can feed power by charging a rechargeable battery, not shown, from a feed terminal (25) that is provided in the notch (23). Such a structure enables convenient and low-cost use without a power supply cable or battery at the time of use. Naturally it is also possible to have a configuration in which power is fed from outside, or a battery is used.

FIG. 6 shows front view of the cosmetic mask according to the present invention, and depicts a state where the mask body (1) and the current generator (2) have been combined. Convexoconcave portions that correspond to the notches (23) are formed in the stimulator fitting section (16) of the mask body (1), to regulate the orientation of the current generator (2).

Mask-side electrodes (240), (241), (242) of the current generator (2) that has been appropriately fitted are energized by being in contact with device-side electrodes (161 a), (161 b), (161 c) that are provided on the inside of the stimulator fitting section (16).

Skin side electrodes (160 b), (161 b), and (162 b) that are integrally formed by a conductor are exposed to the skin side, namely the rear surface of the mask body (1), from the device-side electrodes (160 a), (160 b) and (160 c). Each of the electrodes (160), (161) and (162) constitute arrow shapes radiating out from apexes of a triangle, as shown in FIG. 2 .

FIG. 7 is an explanatory drawing showing usage state of the cosmetic mask of the present invention, and as has already been described the horizontal band (11) is fitted at the back of the head while the vertical band (12) is fitted at the top of the head, and it can be seen that the current generator (2) is then in precise contact with cheeks.

After performing appropriate positioning as described above, respective currents are applied from each of the electrodes (160), (161), (162) to the zygomatic muscles and the masseter muscles, as shown in FIG. 8 .

The zygomatic muscles have a function of lifting saggy cheeks and laugh lines. While they are classified into the greater zygomatic muscle and the lesser zygomatic muscle, with this practical example, a muscle toning effect is achieved by applying current to both of these muscles. The occurrence of dropping of the corners of the mouth due to aging and loss of muscular strength, and laughter lines, double chin, and face line sagging, can be improved by toning the zygomatic muscles.

The masseter muscles are muscles that are responsible for biting force, and fatigue can build up with chewing, teeth clenching etc. Also, there are problems such as a so-called square-jaw arising if masseter muscles are developed due to a person grinding their teeth, which may undesirably alter the shape of the face. Similarly, toning of masseter muscles by electrical stimulation etc., may cause undesirable shaping of the face, which results in an adverse effect in terms of cosmetology.

Application Method 1

With the present invention, in order to apply optimum stimulation to the zygomatic muscles and the masseter muscles, electrodes (160), (161), and (162) are arranged, and after adjusting the mask to a suitable position, current that has been controlled is applied between electrodes.

Specifically, electrical stimulation (30) at a suitable frequency for toning muscles is applied between the electrodes (160) and (161) corresponding to locations of the zygomatic muscles. As shown in FIG. 9 , with this practical example low frequency current of 15 Hz is applied.

Also, electrical stimulation (31) at a suitable frequency for easing muscles is applied between the electrodes (160) and (162) corresponding to locations of the masseter muscles. As shown in FIG. 9 , with this practical example low-frequency current of 33 Hz is applied.

Then, the control section of the current generator (2) performs control to alternately apply current for masseter muscles and current for the zygomatic muscle and perform treatment for 10 minutes.

The scope of this invention is locations that provide stimulation to the zygomatic muscles and masseter muscles, discovered by the inventors from research. As shown in FIG. 8 , the center position between electrodes (160) and (161) corresponding to locations of the zygomatic muscles is preferably at a position L1=76 mm±19 mm, particularly ±5 mm, from the center of the face in a lateral direction, and L2=90 mm+10 mm, particularly ±5 mm, from the lower end of the mask section (10), that is, in an upward direction from a position corresponding to the chin.

As shown FIG. 8 , a center position between electrodes (160) and (162) corresponding to locations of the masseter muscles is preferably at a position of L3=109 mm±10 mm, particularly ±5 mm, from the center of the face in a lateral direction, and L4=63 mm±10 mm, particularly ±5 mm, from a lower end of the mask section (10), that is, in an upward direction from a position corresponding to the chin.

A distance between electrodes (160) and (161), and between electrodes (160) and (162) is preferably 60 mm±15 mm, and zygomatic muscles or masseter muscles between these electrodes are subjected to stimulation.

With a configuration equipped with the stimulator fitting section (16), openings at the above-described corresponding sections for arranging stimulators in the above-described range can be provided.

As a result of tests by the inventors, it was shown that relative values for size of laughter lines are reduced by about 12% by applying controlled low-frequency electrical current to zygomatic muscle locations for 10 minutes. Testing was conducted for three test subjects, and a tendency for improvement was seen in all subjects. Measurements were performed using an Antera 3D skin analyzer.

Application Method 2

The inventors performed more detailed tests, for current application methods, and found the optimum frequency for zygomatic muscles and masseter muscles. Results of these tests are shown in the following.

For three test subjects, electric currents of various frequencies were applied for 10 minutes in an environment of a room temperature of 25° and humidity of 38%, to measure degree of improvement in size and depth of wrinkles.

First, test results for zygomatic muscles are as shown in Table 1.

TABLE 1 Test subject 1 Test subject 2 Test subject 3 Frequency size depth size depth size depth  1 Hz x x x r x x  2 Hz r r i i r r  5 Hz i i i i i i  8 Hz i i i i i i  10 Hz i r i i i i  15 Hz i i i i i i  20 Hz r r i i i i  25 Hz r r x x  33 Hz x x x x x x  50 Hz x x x x x x 100 Hz x x x x x x 200 Hz x x x x x x i: improvement; r: slight improvement; x: no improvement

The above test results show that a frequency applied to zygomatic muscles is effective in a range of 2 Hz to 20 Hz, and particularly in a range of 5 Hz to 20 Hz.

Further, it is also preferable to change application frequency over time in this frequency band. For example, the user can effectively apply electrical stimulation by repeatedly conducting control such as applying electricity at 10 Hz for 10 seconds, and then at 2 Hz for 10 seconds, so that the skin will not become accustomed to the electrical load.

Next, test results for masseter muscles are as shown in Table 2.

TABLE 2 Test subject 1 Test subject 2 Test subject 3 Frequency size depth size depth size depth  1 Hz x x x x x x  2 Hz x x x x x x  5 Hz x x x x x x  8 Hz x x x x x x  10 Hz x x x r x x  15 Hz x x r r r r  20 Hz r r i i i i  25 Hz i i i i i i  33 Hz i i i i i i  50 Hz i i i i i i 100 Hz i i i i i i 200 Hz x x r x r x i: improvement; r: slight improvement; x: no improvement

The above described test results show that a frequency applied to masseter muscles is effective in a range of 20 Hz to 100 Hz.

Further, it is also effective to change application frequency over time in this frequency band. For example, the user can effectively apply electrical stimulation by repeatedly conducting control such as applying electricity at 100 Hz for 10 seconds and then at 20 Hz for 10 seconds, so that the skin will not become accustomed to the electrical load.

The cosmetic mask (1) of the present invention is formed of silicone as has been described above, and in particular, the mask section (10), the horizontal band (11), and the vertical band (12) are integrally formed. It is conventionally known to form a mask using silicone, but with the present invention it is particularly proposed to use silicone of differing hardness for each location.

FIG. 10 is a drawing describing a method of molding the cosmetic mask (1). In FIG. 10(A), silicone materials (40) to (44) of differing hardness are arranged on a mold for forming the cosmetic mask (I), and the mask is formed by direct pressure molding with an upper mold and a lower mold while integrating the materials.

The silicone material (14) is placed on both ends of the horizontal band (11), to form a material having a rubber hardness of 20° that is easily stretchable. Similarly, the silicone material (43) is used on both ends of the vertical band (12).

The silicone material (41) used at locations corresponding to side surfaces of the face, and silicone material (44) used at locations corresponding to lower parts of the cheeks are slightly harder materials, having a rubber hardness of 40°. While the above-described locations impart a gentle touch due to their moderate elasticity, friction with the skin may arise when degree of elasticity is large, and a slightly less elastic material compared to the silicone materials (40), (43) is used at the band sections.

Further, a silicone material (42) having the highest degree of hardness, namely a hardness of 60°, is used in the mask section (10). A material of sufficient hardness is adopted because the above-mention location applies an appropriate tensile force to the face, and also in order to prevent the stimulator fitting section (16) from deforming, and reliably hold the current generator (2).

As a result of molding the cosmetic mask using silicone materials (40) to (44) of differing hardness, the cosmetic mask (1) having different hardness (H1) to (H5) depending on location is completed, as shown in FIG. 10(B). Regarding the above described hardness, hardness H1 and H4 20°, hardness H2 and H5 are 40°, and hardness H4 is 60°.

The above described strengths may be changed arbitrarily. For example, the horizontal band (11) the vertical band (12) may be configured having comparatively low hardness, while the mask section (10) may be configured having comparatively high hardness.

In this way, by changing the hardness of the materials, as well as contributing to improvement in usability of the cosmetic mask, it is possible to achieve a simple structure and reduced cost, and to realize a neat appearance in an integral design.

A specific usage for the cosmetic mask of the present invention is described as follows.

After face washing, condition and sufficiently moisturize the skin using such as skin-care products and lotion. Then apply cosmetic mask (1) to the face, wrap the horizontal band (11) and the vertical band (12) around so as to lift up the cheeks. Fit the previously charged current generator (2) into the cosmetic mask (1) and turn on the current of the current generator (2).

Operate the adjustment buttons (21) and (22) at a preferred strength chosen from six levels, for example. The cosmetic mask automatically turns off after 10 minutes of treatment.

According to the present invention, the cosmetic mask made of highly elastic silicone shapes up the face line by physically lifting up jaw lines, the mouth, and face line. Maintaining an ideal face line state, electrical current is output from a main body, and facial expression muscles are automatically toned. Toning of facial expression muscles is difficult, and it has been conventionally difficult to obtain ideal effects. According to the present invention, electrodes that are predetermined arranged around the laughter lines, the eyes, and the jaw, efficiently contract appropriate muscles. Further, since frequency of electrical current is controlled for each muscle, treatment can be given in a comfortable and effective manner.

Since the current generator is detachable, maintenance such as charging and cleaning, is easy. Also, since the cosmetic mask has no electrical cord, the person wearing it can move around in a room and even do housework.

While description of this practical example has been given as above, change is arbitrarily possible within the scope of the claim descriptions.

For example, the stimulators do not need to be detachable, and may be configured integrally with the mask. As stimulators, only one of either the zygomatic muscle stimulators or the masseter muscle stimulators may be provided, and electrodes may also be provided to tone other muscles, for example, the orbicularis orris or the musculus orbicularis oculi.

Although electrical current to be applied can be any of a low-frequency, medium frequency, or high-frequency, as has been described above, it is necessary to set respectively optimum currents in accordance with the nature of a muscle, using the control section. For example, no electrical stimulation is applied to the venter frontalis muscle, corrugator muscle, or ridge of the nose, that would cause discomfort with low frequency being applied, or control is performed so as to apply electrical current of the frequency that will not cause discomfort. It also keeps laughing muscles from being applied with electrical stimulation which would cause pain if the user wears silver crowns.

The above-mentioned prior art publications disclose configurations to apply electrical current on a general area of the cheeks. However, the configuration that the intensity level or mode of the stimulation is preferably regulated.

The present invention attains these goals, leading to a significant esthetic effect.
